Overview - 4G USB Modem

4G USB Modem is a device which allows like a desktop computer or laptop to access the Internet with very high speed up to 100Mbps or more. Today there are different types of LTE modems on the market that are suitable for various applications such as stationary use as a DSL replacement or mobile browsing, or industrial use M2M connectivity. The Peak speed of 4G USB Modem with LTE module could reach peak download speed up to 100Mbps and download speed at 50Mbps, so many customers call such 4G LTE USB modem as 100Mbps modem. Based on the technology of the data transmission, 4G USB modem could be divided into TDD Modem and FDD Modem.

With a 4G USB dongle, you can always access the internet everywhere. It is a small piece of hardware that you connect to your computer, tablet or laptop and has various functions. In the past, 4G dongles were used as hardware keys (for security) nowadays the USB modems are a simple solution to be able to surf the Internet anywhere and anytime.

The 4G dongle is a USB modem that you plug into the device with which you want to use the internet. Almost all laptops are suitable for internet with a 4G dongle. The only thing that your laptop needs is a USB connection port. After you have installed the software and inserted a SIM card into the 4G modem, you immediately have access to the wireless network of the provider. You can also send and receive SMS, Bluetooth, and infrared signals. To connect to the internet, you may connect to 3G or 4G wireless networks. Based on LTE wireless network. Standard industrial serial port (RS232 / RS485 / TTL) is available. Support dial-up Internet access, Chinese and English text messaging, CSD data transmission and other functions. Suitable for industrial control industry, no need for real-time online, small data volume, serial device wireless data transmission, or LTE narrowband dial-up Internet access. Products are widely used in electric power, environmental monitoring, vehicle, water conservancy, finance, street lamp monitoring, heat pipe network, coal mine, oil field and other industries
